Anonymous session triggering workflow

I have a Retool app which is designed to support anonymous users. One of its features is a button that launches a workflow. Testing it in an incognito window I was surprised to see this button trigger the logon splash screen:

I don't know if this is a new bug, old bug, or actually by design.

Hi @Roland_Alden We are tracking a bug where Workflows triggered via our integration don't work in public apps :disappointed:

The current workaround is to trigger the workflow via a Rest api query
